Definitions
- a method of controlling sorting systems, and a sorting system thus controlled is a method of controlling sorting systems, and a sorting system thus controlled.
- the present invention relates to a method of con ⁇ trolling a sorter system of the type comprising a sorter conveyor having load carrying trays or sections that can be loaded with articles and later, during movement of the conveyor, be actuated to unload the articles in a selective manner to a selected unloading or receiving station among many such stations located along the mov ⁇ ing path of the conveyor.
- a sorter conveyor having load carrying trays or sections that can be loaded with articles and later, during movement of the conveyor, be actuated to unload the articles in a selective manner to a selected unloading or receiving station among many such stations located along the mov ⁇ ing path of the conveyor.
- the single conveyor sections or trays are laterally tiltably arranged such that the unloading may be effected by a selective actu ⁇ ation of associated tilting mechanisms for these trays, but it is also known to invoke the unloading by using stationary deflector means which in a selected unloading station may be introduced into the moving path of the articles for guiding out articles to that particular un
- the unloading stations can be placed rather close to each other and each having an almost minimized dimen ⁇ sion in the conveying direction, whereby it is important that the unloadings be effected with high accuracy, i.e. during the movement of the relevant trays through rela ⁇ tively short, well defined lengths.
- the development has gone in the direction of a central control of these and many other functions in the system, because from a cen ⁇ tral control system it is possible to account for the location of all the trays, when the tray passages are detected at a single place only.
- a central control unit which is informed of the destination code and of the time and place of loading of each article, will be able to actuate the unloading at just the selected unloading station, when only the con ⁇ veyor itself is constructed with the required accuracy, here particularly with respect to a highly uniform pitch of the trays, such that each of the trays will be lo ⁇ cated just at the place that can be calculated based on the number of tray passages subsequent to the passage of each of the trays at the place of detection.
- the invention is based on the recognition that considerable advantages are achievable by working with a decentralized control in connection with the use of local detectors for the passage of the trays at the single unloading stations, and thus the invention breaks with the said general trend of development. It has al ⁇ ready been realized that in large systems with highly developed controlling and supervising functions a limit area for the capacity of commercially available data processing equipment is being reached, and just the concerned sorter systems are very well suited to be subdivided into some different functional entities with coordinated, but otherwise individually controlled func ⁇ tions, such that a really extensive and effective con ⁇ trolling will be achievable in a system which, as a whole, will be relatively cheap.
- the invention proposes to make use of a detectable physical identification marking of the single tray sections of the conveyor, whilst at all loading and unloading stations detector means should be provided, capable of detecting these markings and being connected to a separate control unit that receives information of the destination codes of the articles and of the identi ⁇ ty of the trays on which the articles have been loaded.
- this control unit may in a selective manner be operative to actuate the detector means of the single relevant unloading stations such that these de ⁇ tector means in any given unloading station will be programmed to react on the occurance of a tray unit having just the identification marking, which in connec ⁇ tion with the data read-in is associated with the rele- vant destination code of the article.
- the sensor means at the unloading station may then be adapted to cause an actuation of the unloading means in just this unloading station, whereby this actuation can be effected as a result of a detected arrival of the tray to the relevant position, without any necessity of in the meantime keep ⁇ ing account of the location of all the other tray units.
- At the single receiving stations may be provided local control units that will not only react to the arrival of a designated tray unit, but also serve to control and check the operative events in connection with the single unloadings and the collecting of the unloaded articles, e.g. control of the reception by each unloading and a general control for avoiding overfilling of an associated collection container. All this may very well amount to quite many control and check functions for each single receiving station, and already as far as the wiring work is concerned a noticeable saving will be achieved when it is sufficient to establish local con ⁇ nections to the respective control units in stead of many connections between a central data processor and all the single sensors and operations units. Already in fairly large systems this saving alone may amount to between a half and a whole million of Danish kroner.
- the system shown comprises a round-going sorter conveyor having a conveyor chassis 2 and, moving there- along, a row 4 of tray units 6 each provided with a laterally tiltable carrier tray 8.
- the row 4 can be a coherent chain of units, but it is also possible to use separate cart units 6 or cart trains with several tray units, when suitable means for the driving thereof are provided.
- the row 4 passes a loading area A, in which one or more loading stations 10 are arranged , and thereafter an unloading area B that may stretch over practically all the remaining length of the conveyor.
- At each station 12 is provided a mechanism that can be actuated for effect ⁇ ing a lateral tilting of a passing tray 8 for unloading of the goods on the tray to the respective container 14.
- a coding in unit 18 is provided, by means of which the successively arriving articles to be sorted are coded into the system with respect to their destinations, such that they can later on be unloaded at the correct unloading stations 12, and at each loading station 10 there is also provided an inlet control unit 20 serving to control the delivery of the articles such that in a well defined manner they will be delivered to suitably empty trays; when more loading stations 10 are arranged in series it is of course required to make sure that the articles are de ⁇ livered to a tray which has not already been loaded.
- the coding in units 18 are connected to a common processor unit 22, named "code master”, which can be adapted so as to supervise the principal correctness of the keyed or otherwise read in destination data for successively supplied transport articles.
- code master can be adapted so as to supervise the principal correctness of the keyed or otherwise read in destination data for successively supplied transport articles.
- Such a control may well be executed in a common control unit 22 without loading any superior processor control unit.
- the unit 22 is connected with such a superior processor 24 (“sorter master”) , to which it transfers the checked destination data for the single supplied articles to be handled.
- the inlet or loading control units 20 are connected with a common control unit or "intro ⁇ duction master" 26. While the single units 20 can super ⁇ vise various functions with respect to a correct intro ⁇ duction of the articles, including reception of infor ⁇ mation as to the identity of the tray being loaded, the introduction master 26 should only be able to give the relevant loading orders and thereafter inform the sorter master 24 of the departure of the different trays after a successful loading thereof, which will enable the sorter master to transfer information of correlated tray numbers and destination codes to an "unloading master" 28 that will distribute the informations to individual unloading control units 30.
- introduction master 26 should only be able to give the relevant loading orders and thereafter inform the sorter master 24 of the departure of the different trays after a successful loading thereof, which will enable the sorter master to transfer information of correlated tray numbers and destination codes to an "unloading master" 28 that will distribute the informations to individual unloading control units 30.
- a sensor 32 in each unloading station these units may be actuated by arrival of a tray unit 6,8 that has been destination coded for just the particular unloading station. Then the unit 30 may serve to control the tilting off of the article, e.g. also by checking the passage of the articles along the associated chute 16, e.g. by the article breaking a light beam between a lamp 34 and a photocell 36. The same photocell may be used for checking that the con ⁇ tainer 14 is not about to be overfilled; an alarm signal as to such an overfilling should of course be brought to the master 28 concurrently with being used for a block ⁇ ing of the tilting off function, but otherwise the master 28 will not need to be loaded by current control or check functions in the various unloading stations. As these stations may be spread over a large area this will imply that a lot of wiring can be saved, compared with the heavy wiring otherwise necessary between a central control unit and all the detailed sensors and actuators in all of the unloading stations.
- a further master, designated 38, is a "machine condition master", which is likewise coupled to the sorter master 24 and is connected with different rele ⁇ vant sensors for the condition of the moved system, e.g. a sensor 40 checking that all trays 8 are tilted back to a horizontal position before they reenter the loading zone A.
- the employed driving system may be controlled and checked via a separate master 42.
- a "managing master" 46 In front of the sorter master 24 is arranged a "managing master" 46 that can be used for more superior functions such as accounting control, selection of un ⁇ loading stations in response to changed requirements, indication of free capacity, etc.
- the identification marking of the tray units 6,8 may in a simple manner be a purely physical marking of a binary code which is dynamically readable by the passage of the sensors 30, e.g. a plate strip 44 mounted edge ⁇ wise at a side area of these units and shaped with a row of holes/not-holes for the marking of the codes. How ⁇ ever, the invention is not limited to any particular arrangement in this respect.
- tray units 6,8 will not even need to be coupled together, as the single units or groups of units may be designed as separately movable elements that will just, of course, require a suitable driving system, e.g. con ⁇ sisting of a plurality of linear motors arranged evenly distributed all along the length of the conveyor.
- a suitable driving system e.g. con ⁇ sisting of a plurality of linear motors arranged evenly distributed all along the length of the conveyor.
- This can be an attractive possibility in very extensive sy ⁇ stems, in which the capacity requirements do not justify the use of a continuous row of closely juxtaposed tray units. Quite long stretches may occur in which there are no unloading stations, and it will be possible, then, to let the cart elements move with an increased speed along such free stretches, whereby the capacity of the system can be increased without using additional cart elements.
